Application lefl June 4,

To c?! fui/rom. may' courre/rn.'

Be it lmownthat l, Casimir J. Woon, a citir/.en olf the United States, residing' at San lfrancisce, in the county oi San Francisco and tltate ci California,have ini'ented cer tain new and useitul. improvements in Sepa ratorsand Driers, oit which the `following is a specification.

lily invention is a separator and drier, particularly usefull t'or separating the larger from the smaller particlcsotlsawdust and dryingthem. p y

My invention is illustrated in` the accom` panying drawings which form apart oi? this specification. y

tcflerring to the drawings:

Figure 1 is a view partly in side elevation and partly in section of my invention.

Figure 2 is a transverse vertical section of my invention taken on line 2-2 of Fig. 1 looking in the direction of arrows.

Figure 3 is a vertical, sectional view oi' the valve.

Figure l is a side elevation ol a modified 'lorm of my invention.

Figure 5 is a sectional view taken on line 5v5-of Fig. 4 looking in direction of the arrows.

Figure 6 is a side elevation of another modiiied form of my invention.

ln the drawings, 1 indicates a tan blower, to the inlet of which is connected a duct 2 leading from an air heating chamber 3. The chamber 3 has an air inlet 4l, and a pipe 5 extends through the chamber and is coiled therein through which steam or hot water may be circulated for heating the air passing through the chamber. A valve 6 conH trols the passage of steam or hot water through the pipe 5. A hopper 7 is connected by duct 8 to duct 2. A duct 9 leads 'from the outlet of the blower 1 to the lower small end ot a funnel-shaped separating and drying chamberl 10, a valve casing 11 being interposed between the duct and receptacle. The bottom of the valve casing is formed by two converging walls each having ports 13 and 14 therein, respectively, and. the casing 'further has a port 15 on its upper wall. A valve 12 is pivotally mounted in the casing 11 between the inlet 13 and the outlet 14 in order that it may be operated to alternately control each ot the latter ports 13 and 14:, the port 15 communicating with the chamber 10 being open. A. handle 16 is secured to the pivot of the 4'valve closure 1 2 outside olfv Specification of letters Fatent.

:spout 17 leads from the valve outlet lll. ioo

y The 11i oi the chamber 10 is closed by ai'i'upper wa l i8 in the center el? which is an outlet lllaround which a flange 20 depends from the wall 18, forming `an annular space 21 between the langeahd the side wall ot the chamber. The opening 19 is directly over and in central alignment with the lower open end oi the chamber 10 which communicates \'\.'i ththe port 15 of valve 41.1.

l he operation ot my invention is as follows Sawrlust is lied into the hopper 7 and drops through dilctlinto duct 2. The blower l daws al trom ehamberl andthe sawdust in duct 2 into itself and forces the air and sawdust through duct 9 and valve casing 11 into chamber 10. The hner particles of the sawdust are blown out of the chamber through opening 19 while the larger particles spread and are agitated and dried within the chamber by the air, thus separating the larger particles oi sawdust from the Vfiner particles. llpon swinging the valve closure 12 away fromoutlet 14 and over inlet 13, and stopping the blower 1, the larger particles ot dried sawdust drop ltrom the chamber 10 through valve 11, port 14- and spout 17.

ln the modified "lio-rm of my invention shown in 4 and 5. the duct 9 is connected to a plurality oi separating and drying chambers 10 by branch ducts 25. Valves 26 and 27 are placed in the duct 9. All of the chambers l0 receive and separate and dry sawdust when the valves 26 and 27 are epen. Upon closing the valve 26 only the chamber nearest the blower is put in operation. lllpon opening the valve 26 and closing the valve 27 the two chambers nearest the blower are put in operation while the remaining chamber is put out of operation. The chambers may be independently con trolled by their valves 11. `While one chamber is out ot operation and the separated sawdust is being removed. therefrom, another chamber may be operated. The advantage oi this torni ot my invention is that it may be operated continuously, it not being :necessary to stop the blower to remove the separated sawdust Yfrom a chamber.

The modified form of my invention shown in Fig. 6 is similar to the form shown in Figs. 1, 2, and 3, except that the upper wall of the separating chamber 10 converges to the outlet lll and a duet 30 leads from said :he valve casing for operating the valve.` il;

outlet to fan 3l. for drawing the finer savvdust from said chamber, the heavier particles being discharged through the pipe 17 upon suitable operation of the valve in the valve casing 1l.

Having` described my invention, l claim:

l. A device of the character described comprising a separating chamber in which granular material is introduced and suspended therein in a column of air, a valve casing arranged below the separator and communicating` therewith, said casing having an inlet port therein for admitting said air to the separator and having;v an outlet port in a lower portion thereof, and a valve for controlling said ports whereby the separator will discharge through said valve casing and said outlet therein when the inlet port in the casing is closed.

2. A device of the character described, comprising means for introducing granular material into a current of air, a valve casing having a bottom thereof` composed of two converging Walls, each formed with a port, one of said ports being connected with said means and the other providing; a discharge outlet7 a single valve pivoted at the confluence oi said walls and between said ports 'to alternately close the same, a. separating and drying chamber arranged over the valve casing' and communi ating with an upper portion thereof and posi. tioned to discharge through the valve casing and the outlet therein, when the inlet port in the casing is closed.

3. A device of the character describcvl` comprising' means for introducing granular material into a current ot air. a conduit leading` im the delivery side oi said means and hin/'ing` a plurality ot spaced eut-oil" valves therein providing` a plurality o'l stations in the conduit. a pliuality oi separating' hay bers each connected with one et the stations` and means 'for controlling communication between each chamber and its respective station. whereby selected communication may be established between the blower and any of said chambers or all oit said chambers.
